TOPAZ THROATED HUMMING-BIRD. 



Trochilus pella. LINN^US. Variety. 

 PLATE XXV. 



WE have given a copy from Lesson of a curious 

 variety of this bird, exhibiting an imperfect state of 

 albino, and in which the pure white feathers con- 

 trast beautifully with the gorgeous plumage of the 

 other parts, which did not seem to want any thing of 

 their brilliancy. It has been thought by some that 

 the occurrence of white feathers, or of pale coloured 

 varieties, did not take place in those birds having 

 plumage of shining or metallic lustre. Of this the 

 accompanying plate will be a proof to the contrary, 

 where it is exhibited in one possessing those qualities 

 to the utmost ; and we have specimens of one or two 

 other species where it also occurs. As familiar in- 

 stances of it, we may mention the common Starling, 

 Pheasant, and Peacock.
